Application led October 8, 1914. Serial 865,751.V

To all whom t may concern Be it known that YVYLLIAM D; RoBEnrsHAw, a citizen offthe United States, and a resident of Greenville, county of Vifash.-l

ington, and State Zof Mississippi, have made certain new and useful Improvementsin Devices-for Killing Boll-Veevils, of whlch the following is' a specification.

' out injuring the latter.

A further object of my invention is to.

provide a device of the type described lhaving pans or receptacles which may be filled withoil into which the boll weevils are projected, thereby insuring the death of the in- A portions of the bow 1 are bent inwardly, as

sectsand at the same time collecting them.

A further objectot my invention is to provide adevice of the type described in which springsare sc disposed as to most .electively agitate the growing plant so as Vvtoinsure the-shaking. of the insects from ythe plant and their projectioninto the ref A further object of my invention is4 to Y provide a device of the type described which will eifectively gather and kill the boll.

Other objects and advantages will appearA l in? the following specification and the novel feiitures of the invention will be'particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawing forming a. part of thisapplication in which similar reference characv ters indicate like parts in the several views, and in which, A

Figure 1 is a.' plan view of the device, certain portionsbeing omitted lfor the' sake of cleanness, Fig. 2 is a central longitudinal section through the device, Fig. 3 is a section along the line 3-3 of Fig. 1, looking in the direction of the arrows, and Fig.V 4 is a section along the line 4.--4 of Fig. 2 looking in the direction of the arrows.

In carrying'oout my invention I provide a main tran's'f'vjerse bow 1 which may be made of metal bij other suitable material. On

bottom. thereof I provide U-shaped brackets 2 which are secured to thevb'ow by means of bolts 3 or in any other suitable manner. The bow 1 and the .brackets 2. are provided y the` inner side ofthe bow 1 toward the with registering openings for the reception of the axle bolts 4, these bolts being secured in position byA means of the 'nuts 5.

from Fig; 4 forms the'joilrnal for the hub 6 of the wheel 7, the wheel being secured in position by .meansof a nut 8. v As willbe seenv from Fig14 'two wheels are provided and the construction of Veach wheel is precisely vsimilar to that of the other one. y

Secured to the mali-n bow 1 at the central upper portion thereof is a longitudinal bar shown at l", in ordler vto form supports for the .receptacles 12. .The portions lmay be soldered to the bottom of the 'receptacles or otherwise secured and preferably'- ass through U-shaped brackets 13 on the bo. tomv of 'the pans.V The 4ends of the bows llgare secured to vthe upper edges of the pans so that the two pans 12 are suspended at their outer edgesand project towardy one another, their 'inner vedges being spaced apart to provide a passage for the stems of the plants.

As will be seen from Fig. 4 the forward The A outer end of the axle bolt as will be seen 9'between which and a lower longitudinal from Fig. 3 the bottom l .80

edges of the pans 12 are inclined outwardly,

as shown at 12Y, and these edges, as well as the lnnerredges ofthe pans are curved so'as not to present any sharp edges to the stems of the plant. vThe pans 12 are divided into compartments by means of a series of transverse partitions 12X. Secured to theauXiliary bows 11 area, number of springs 14.

The end of each shown at 14". for a purpose'hereinafter de- .These springs are linclined rearwardly and extend toward the center.

spring is bent rearwardly and is fluted, fas' geredelation both horizontally and .fverti- I cally. Over the outside oitv the yframe, formed by the. bows, is a covering of fine wire netting 15 or canvas.

may be secured to the longitudinal lmember' 9 at the rear of the device inprder to propel the same.

A handle 16" cerises tbe From the foregoing description of the verious parts of the device the operation thereof may readily be understood.

The compartments formed oy the psrtitions l2 may be llecl 'with oil or other suitable liquid which is fetal to boil Weer/ils. The device is propelle` along,c the rows in snob e that tbestenis or stalks of the plant poss into the opening formell by the flivergingr en ils i2", :incl from thence intov the space between the opposed pens. The frame formeel by the bows is designed to oe large enough to permit the plants to enter underneath the bows. the springs le corse-in Contact rf'tli tbe various 'portions of the plant they are forced aside and. owing to the flute-,d forni of their ends there is s, vibratory motion given the which ent agitation o tbe plant,

on" the insee"c or recepliocl s u i contain e iiosiority are l; reel by the resiliency oi the springs the device is propeleil ov e rovv of cotton pls; the iron o n rings in lor' cking cil 'the boil 'aveevis is continw ous, sin as steterl above s iings are in stogserecl relation. The result is that the plants are reecl from the insects lie device liars the added advantage that it collects the insects which are lrnockerlor of olie plant. The, oil may be ignited ivithout removine it Yfrom the receptacles, anti. thus the insects be totally destroyed, or the oil containing the insects nia-y be poured out into any suitable receptacle and ignited..

I claim:

l. ln a device for killing boli WeevilS, a frame comprisingaplurality of bows spaced spart, saicl bows being secured together, a pair of open receptacles carried by said bows at their lower ends, said receptacles'being spaced spart to provide a passage for the stems of the plants, andn'means carried by 'lle Liseoer the bows and arranged to engage the plants during the movement of the frame for sgitating the plants and thereby projecting the boil weevil into the' receptacles, seid vlestntunefl means comprising a plurality of inwardly projecting spring members, said spring' members being carried by ssicl bows and beinglinclined rearwardly, tbeiecr enrls of spring members being viluted.
